Keeping with tradition, Middleton -- who wore a vintage Amanda Wakeley suit -- walked a step behind her future husband (just as PrincePhilip has to walk behind The Queen).

The first stop on the couple's day-long visit? A midday arrival at the opening of the Darwen Aldridge Community Academy. Despite the dismal weather, William and his future wife smiled and waved to the crowd from under the safety of their umbrellas.

Their second and final stop of the day will be at the nearby Witton Country Park in Blackburn, where thousands of fans are already awaiting their arrival. While there, they will observe a series of sporting events and meet with a group of athletes and coaches.
